Check Digit Verification of cas no

The CAS Registry Mumber 91226-54-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,2,2 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91226-54:
(7*9)+(6*1)+(5*2)+(4*2)+(3*6)+(2*5)+(1*4)=119
119 % 10 = 9
So 91226-54-9 is a valid CAS Registry Number.

The Synthesis and Chemistry of Azolenines. Part 3. Some Reactions of 4H-Pyrazole Quaternary Salts

Katritzky, Alan R.,Lam, Jamshed N.,Rubio, Olga,Sammes, Michael P.

, p. 947 - 952 (2007/10/02)

The preparation of some novel 4H-pyrazolium salts is described.Unlike the structurally related 2H-imidazolium salts (1), the metho-salts (2) of 4H-pyrazoles show no exchange with deuterium at the N-methyl protons.Exchange occurs readily at a 5-methyl grou
